PEEK backup rings are used to prevent O-rings from being squeezed out and damaged in the gap under high temperature and high pressure combined environment. Although using backup ring is not necessary, it is a cost-effective solution to extend the service life of seals.
PEEK backup rings have obvious performance advantages among many material backup rings. They have similar chemical corrosion resistance to PTFE. Their prominent characteristics are that they can withstand higher temperatures (up to 260C° for long-term use and up to 300C° for instantaneous use) and high pressures and have higher mechanical strength (tensile strength is 132-148Mpa).
